Abstract
An overload-resistant pressure measuring sensor includes a pressure sensor arranged in an interior of a sensor housing and can be exposed, through an opening in the sensor housing, to a medium under pressure of up to 1000 bar. The medium may be a hydrogen-containing medium and can be measured with high measurement accuracy. The pressure sensor is mounted on connection elements protruding into the interior and free-standing in the interior such that the pressure sensor is exposed to the pressure prevailing in the interior on all sides. The pressure sensor includes two ceramic measuring bodies connected to one another while enclosing a pressure chamber, and are each deformable by the pressure acting thereon, and further includes an electromechanical transducer which converts a mechanical variable that is dependent on a sum of the pressure-dependent deformations of both measuring bodies into a measurable electrical measurement variable.
